| 中文摘要: |
| 船体型线设计是船舶设计过程中的重要环节. 在对各种现有的基于数学船型表达的型线设计方法进行优缺点比较的基础上，提出了基于横向函数法的船体型线设计方法，即先用数学函数表达纵剖线，然后沿宽度方向将变化的纵剖线的参数表达为横向的函数关系，并举例对该方法的实用性及局限性进行了分析. 经研究认为可以使用横向函数法解决型线设计中的某些特殊问题，如不对称船型和破损船型，将其与现有方法配合使用可以更好地进行型线设计. |

| Design of hull lines plays an important role in the process of ship design. Depending on comparison between the advantages and disadvantages of existing design methods of hull lines which are based on mathematical expression, a new method named design method of hull lines based on transverse function method is put forward. The main idea of this method firstly describes longitudinal lines using mathematical function, then relates the variational parameter of longitudinal lines to transverse function in width. Practicability and limitations of the method are analyzed by illustration. In conclusion, some particular problems in design of hull lines such as dissymmetrical hulls and damaged hulls, can be settled by transverse function method. Moreover, cooperating the method with existing ones will lead to better use. |
